Etymotic ER3SE Studio Edition Earphones, Black

The ER3SE is a high-sensitivity single driver in-ear monitor (IEM) renowned for its exceptional accuracy in audio reproduction. The IEM shells are meticulously crafted from anodized aluminum, with tight tolerances to ensure a compact and efficient design. The use of a single balanced armature (BA) driver provides an easy-to-drive IEM with excellent precision.

The ER3SE is also recognized for its remarkable passive noise isolation, offering up to 42 dB of attenuation. This feature makes the ER3SE a popular choice among sound engineers, audiophiles, and budget-conscious consumers seeking high-quality in-ear monitors.

The ER3SE and ER3XR are the two models within the ER3 series, both utilizing the same high-sensitivity Balanced Armature driver that is easily driven, even without an amplifier. The distinction between the two lies in the tuning of the lower frequencies. The ER3SE is designed to be neutral and flat, while the ER3XR is tuned for a high-energy, emphasized bass response.

The ER3SE is an excellent choice for audio creators, musicians, and those who prefer to listen to music as it was originally recorded. Conversely, the ER3XR is ideal for individuals who enjoy a more pronounced bass presence.

Etymotic's objective in tuning their IEMs is to achieve a flat frequency response that takes into account the resonance in the average ear canal. This results in a slight "hump" in the 2-5k region, which compensates for the resonance and delivers a perceptibly flat frequency response. Etymotic's target frequency response graph is the product of more than 20 years of research and expertise in human hearing and acoustics.

The goal in tuning IEMs is to accurately reproduce a live performance, factoring in the acoustic properties of the ear. This requires a slight "hump" in the frequency response graph to compensate for the acoustic resonance and horn effects of the ear, ensuring a flat frequency response as perceived by the eardrum.

The ER3SE and ER3XR feature the following specifications:

Frequency Response: 20 Hz – 16 kHz Transducers: Single high-performance balanced armature per channel Precision machined metal bodies; high-performance Balanced Armature micro-drivers 4ft reinforced detachable cables with 3.5mm Gold plated stereo Plug and MMCX connectors Noise Isolation: 35dB using silicone ear tips, 42dB using foam ear tips
